Not the right answer for me. Why punish other clubs and fans who enjoy a pint or two whilst watching the game?
Those scenes today were an absolute disgrace. The answer is simple. Firstly, the RFL must deal with the on field issues. I can see a couple of 2-3 match bans for players from both sides.
Secondly, both clubs should be heavily fined for the off field incidents. I would have to see it again but I didn't see many stewards there. Use the camera's available to pick out the main instigators and culprits. Hand each and every one of them a total ban from entering a Rugby League Stadium ever again.
